Updates to Team Fortress 2, Counter-Strike: Source, Day of Defeat: Source and Half-Life 2: Deathmatch have been released. The updates will be applied automatically when your Steam client is restarted. The major changes include:

Source Engine Changes (CS:S, DoD:S, TF2, HL2:DM)

[Windows] Updated mouse configuration UI to support raw input and acceleration; added tooltips to some of the options

[Windows] Fixed UI tooltips so that they display correctly on first hover
